"... with a little help from my friends", part III

25 years ago this week, I left the Natural Resources Canada to start a business with Teknika. I was encouraged (if not pushed) along by a fellow geologist, who had a comprehensive petroleum geocomputing system at Husky in Calgary - his colleague encouraged me at University of Calgary to take a class in computer sciences, the same department where Jim Gosling later on created Java. I teamed up then with a brilliant surveyor who delivered a video-tracing system. These were the DOS days when we used AutoCAD as the graphics prior to Windows. And as my banner note states, he spatialised AutoCAD with a 10Kb DOS kernel that might've given Intergraph and Esri a run for their money, had AutoDesk picked it up at the time.

Clouds gathering over the horizon, part V

Will spectacular outages of AWS and now BT cloud services casts a pall over the excitement that has reached even politicians? And now comes this geopolitical issue only hinted at by MSFT's tribulations in Europe over Internet Explorer. This posted in Germany (Google Chrome will translate this page for you) by Ruth Lang - 'SVG queen' to Dino Ravnic 'web vector king'.

Your team is your friend

I am so proud of my teams at client sites and in our office! One team achieved in 6 months at one site what many thought would take years - to integrate surface and subsurface exploration and production infrastructure for an oilfield in 3D+time. Another team created just this week a real-time GIS data capture system that reduces to 4 steps what took 10 on paper - and of those only the first one is manual.

"Vectors are your friend"

HTML5 Canvas was a natural extension for giscloud.com:  Its distinction is to post vectors on the web, overlaying rasters like any GIS, and with a optional postGIS running in the background. Not only does this speed up drawing maps on the web, it also allows massive amounts - in the millions of points, lines and polygons - to render PDQ (pretty darn quickly) - thus Vectors are your friend - my moderately complex maps benefit from even clean&crisper renderings of polygons as expected and of tiled images especially.

Be the weatherman for others

Last week I posted dust and wind data germane to Kuwait in my banner map. This week take the same layers and mash them up with another service: Here I took a service from ESRI(France) to post volunteer ride-sharers (covoiturage) to their SIG 2011, and added weather and urban data, just to show how easy it is to augment existing offerings.

Be your own weatherman

Dust storms are what you look out for in Kuwait. The banner map was a very simple way for me to create my own weather map:

1. where are the dust clouds?
2. what is the wind direction?
3. when will Kuwait get one?

New book and banner ads

Geography is the basis of "Entre deux Eaux", my new book of poetry and prose on my travels and travails - check the publisher icon to the right, and soon on Amazon and Barnes&Noble in the banner - so much so that the book cover image is a snapshot of my three-year old web map:

New look and banner maps

You will have noticed that the banner picture is now a dynamic map... The monsoon season has passed and the hurricane season is starting: So let's augment the previous image of dust cover with NOAA's wind speed map too, shall we? You can zoon in&out or pan across the banner too! And you may have to "wait a sec" for the display to refresh. But I simply used the "embed" feature of ArcGIS Explorer maps, available from other packages too, and reformatted the entire banner to accommodate that.

2nd anniversary blog

[30 Sept. udate: I posted my Google Page Rank to the right: its jump from 2 on my website to 4 here is a further indication of how dynamic social media improve over static web. I also wrote on further social media dynamics I used in oilelefant.com last year.]

Hard to believe a year's gone by since my first anniversary blog! I compiled a few stats and posted them on Google Docs, here they are. NOTE: I don't have data where a premium is charged for it.

Simple Feature or Full Feature Specification for OGC?

The issue of how to write-to and read-from geographic databases has been around for quite some time. Esri shapefiles were a runaway success partly because of their open specification. As we moved onto spatial databases, the Open Geospatial Consortium (OGC) offered the simple feature specification (SFS) that all the players could read to or write from. This came in especially handy for consuming web mapping services (those and many other specifications have grown since). But it gets trickier when it comes to reading from and writing to spatial databases generically. By that I mean not from the native application but from others', like with shape files.
